The spinning floors, hung like rings around an immobile cement core, would offer residents a constantly changing view of the Persian Gulf and the city's futuristic skyline. A few penthouse villas would spin on command using a voice-activated computer. The motion of the rest of the building would be choreographed in patterns that could be altered over time. Speaking at a news conference in New York on Tuesday, the building's designer, David Fisher, declared that his tower will revolutionize the way skyscrapers are made -- a claim that might strike some as excessively bold. Fisher acknowledges that he is not well known, has never built a skyscraper before and hasn't practiced architecture regularly in decades. But he insisted his lack of experience wouldn't stop him from completing the project, which has attracted top design talent, including Leslie E. Robertson, the structural engineer for the World Trade Center and the Shanghai World Financial Center. "I did not design skyscrapers, but I feel ready to do so," Fisher said. Twisting floors are just one of several futuristic features in the building, the first of several Fisher hopes to build with a similar design. Giant wind turbines installed between every floor, he said, will generate enough electricity to ...
